Astronomers report Earth-like rainfall on other planets

According to new research, liquid precipitation behaves roughly the same throughout the galaxy — whether it rains water on Earth, ammonia on Jupiter or liquified methane on Saturn’s moon Titan. The new study, “The Physics of Falling Raindrops in Diverse Planetary Atmospheres,” published in the April 2021 edition of JGR Planets, proposes a set of equations astronomers can use to predict the shape, velocity and evaporation rates of raindrops on other planets.
